S58 Midpipe For BMW G80 M3, G82 M4, G83 M4 Including Competition - ARM MotorsportsThe ARM S58 Midpipe upgrade is engineered to unlock the aggressive exhaust character of your G80 M3 or G82 M4. By removing the secondary catalytic converters and the two center resonators, this midpipe significantly enhances the sound of your S58 powered BMW. At the same time, it retains the factory muffler, so you can still control the exhaust valveskeeping them closed for a quieter, refined tone or opening them for maximum volume and performance
The ARM S58 Midpipe upgrade is engineered to unlock the aggressive exhaust character of your G80 M3 or G82 M4. By removing the secondary catalytic converters and the two center resonators, this midpipe significantly enhances the sound of your S58-powered BMW. At the same time, it retains the factory muffler, so you can still control the exhaust valves—keeping them closed for a quieter, refined tone or opening them for maximum volume and performance sound.
Enhance the Sound of Your S58
The ARM S58 Midpipe not only increases overall exhaust volume but also transforms the tone into something far more distinctive than a standard G80 M3. It also makes the signature exhaust burbles more noticeable, even with the factory tune.
The G82 M4 featured in the video below is equipped with both the ARM S58 Midpipe and ARM S58 Downpipes. When paired together, the midpipes and downpipes deliver an even louder and more aggressive exhaust note compared to running the midpipe alone.

The ARM S58 Midpipe then transitions to the X-Pipe section of the exhaust via the slip-fit connections on either side. The X-Pipe is the heart of the ARM S58 Midpipe and is where the magic happens. The sound waves of each bank of your S58 engine are combined to produce a much more exotic and richer exhaust note. The X-Pipe section lives above the OEM brace with ample clearance, there is no need to install a larger brace.
From the X-Pipe section the ARM S58 Midpipe upgrade transitions back to the OEM muffler, which allows full use of the OEM exhaust valves. This gives you the freedom to choose between open and closed exhaust flaps, controlling the volume your G80 M3/M4 produces. To get a look to match your ARM S58 Midpipe check out the ARM S58 Exhaust Tips.
The ARM S58 Midpipe will secure to the exhaust hanger on the driver's side using a standard exhaust hanger prong. It is secured to the passenger's side using the OEM style mounting bracket. These help the exhaust from jostling around during aggressive driving.
